Law enforcement said Monday that it is declining at this time to pursue charges against a man who shot and killed another man over the weekend in St. Paul.

The shooting occurred Saturday shortly after midnight near Payne and E. Arlington avenues, police said.

Officers located the shooting victim in an alley in the 600 block of Arlington. Police identified him as Antuan D. Jones, 41, of St Paul.

A 19-year-old St. Paul man reported his role in the incident to investigators, gave a statement and turned over the gun he used, police said. He was booked into jail about an hour after the shooting and released late Saturday morning.

"In consultation with the Ramsey County Attorney's Office, this male was released pending further investigation," a police statement read. "A second gun was located on the crime scene."

Police have not addressed a possible motive, nor have they said whether the shooting was a case of self-defense or whether the gunman had a permit to carry a weapon.

Anyone under age 21 could not get a government-issued permit to carry a gun in public in Minnesota until last month, when a federal judge struck down the law barring 18- to 20-year-olds from obtaining a permit.

There have been 15 homicides in St. Paul this year. There were 18 at this point last year, according to a Star Tribune database.
